FLOUR-SIFTER.

Specification of Letters Patent.

Patented June 28, 1921.

Application filed January 17, 1921. Serial No. 437,678.

To all whom it may concern Be it known that I, DANIEL SCHNEIDER, a citizen of the United States, residing at Lodi, county of San Joaquin, State of California, have invented certain new and useful Improvements in Flour-Sifters; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in flour sifters such as are used almost universally in household and all other kitchens.

The invention further relates particularly to one-hand flour sifters of the type shown in United States Letters Patent No. 1,188,840, granted me June 27th, 191.6, the principal object of the present invention being to alter the construction embodied in the above mentioned patent in such a manner as to render the device more easily manipulated in that the operating means is applied to be used in connection with that form of holding handle to which all housewives and cooks are accustomed through using the old style sifters.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of I the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views.

Figure 1 is a side elevation of the device.

Fig. 2 is a sectional elevation of the sifter, taken on a plane at right angles to Fig. 1.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 denotes a receptacle, open at top and bottom, and preferably cylindrical and of a general shape andsize such as is ordinarily provided.

This receptacle has as usual a conven bottom member 2 formed of wire mesh or screening, against which agitator blades 3 are adapted to pass closely, being substantially concentric therewith, said blades be ing mounted on a shaft 4 Xtending transversely of the receptacle above the bottom 2, and through one side of the receptacle at which end the shaft is secured to a flat handle member 5 extending downwardly and at right angles to said shaft alongside the receptacle, and substantially radial with said receptacle.

Fixed to the receptacle 1, is a handle member 6, substantially parallel to the side of the receptacle and extending downwardly at an angle wlth the perpendicular, and being positioned to one side of the end of the shaft 4: and handle 5.

In order to maintain the two handles normally at a downward vertical angle with each other, a coil spring 7 is wrapped around the shaft 4:, one end being projected at a tangent and hence through and held by the sides of the receptacle 1 as at 8, and the other end engaging one of the blades 3 as shown at 9. This spring is arranged, as indicated, to move the handle 5 away from the handle 6 and increase the angle therebetween, such movement being limited by the uppermost blade 3 bearing against the projected portion 8 of the spring.

To operate the device, the receptacle is grasped by the handle 6, certain of the fingers being outstretched at the same time to grasp the handle 5. By then closing the hand, the handle 5 is moved toward the handle 6, which causes the blades 3 to sweep across the bottom 2, sifting the flour.

As soon as the hand pressure is removed, the handle 5 will move back to its normal and original position, on account of the pres sure exerted by the spring to effect this end.

The contraction and relaxation of the hand may then be repeated as long as is desired or necessary to sift the flour, the blades of course reciprocating across the bottom all the while.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfils the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to and do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is:

1. In a flour sifter, an agitator, a transverse shaft on which the agitator is mounted, a fixed handle on the receptacle to one side of the shaft, and a handle attached to the shaft outside the receptacle and normally positioned at a downward vertical angle therewith.

2. In a flour sifter, an agitator, a trans-.

verse shaft on which the agitator is mounted, a fixed handle on the receptacle toone side of the shaft with a downward vertical angle with respect to the vertical plane of the shaft, "a handleattached to the shaft extending parallel to the axis of the receptacle and arranged to be grasped in common with the fixed handle, and spring means on the ,with the fixed handle, spring means on the shaft and arranged to normally hold the shaft-handle at an angle to the fixed handle,

and means whereby such movement may be limited.

l. In a flourvsifter, an agitato g'a transverse shaft on which the agitator is mounted, a fixed handle on the receptacle to one side of the shaft, a handle attached to the shaft and arranged to be grasped in common with the fixed handle, and a coil spring about the shaft, one end projecting away from the shaft for a certain distance and being their secured to the receptacle, and the other end bearing against the agitator, the spring being arranged to exert its pressure to cause the shaft-handle to normally lieat an angle to the fixed handle and the agitator being then arranged to abut against the tangential projection of the spring;

5. In a flour sifter, an agitator, a transverse shaft on which the agitator is mount ed, a fixed vertical handle on the sifter positioned, to oneside of the shaft with a downwardvertical angle relative to the vertical plane of the shaft, a fiat handle attached to the shaft and normally including a downward vertical angle 'with the fixed handle, said flat portion lying substantially radial with respect to the sifter, and spring means on the shaft for normally maintaining a predetermined angle between the handles.

In testimony whereof I afiix my signature.

DANIEL SCHNEIDER.
